ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 940,863, dated. April 19, 1881.

Application filed January 521, 1881. (No model.)

To all u'bom i't mag concern l Be it known that I, Evnancrcu H. BARNEY, a Citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Roller-Skates, of which the following is a specification'.

This invention relates to the details of 0011- struction of aroller-skate which provide means for moving the forward axle thereof to different positions under the foot and there properly securing it to an improved axle-skein, and an improved axle-retraoting spring, the object being to enable a skater to set the axle Of a roller-skate at such a point forward or back of the center of his foot as may best suit the peculiar requirements of each wearer, to provide means for conveniently and effectually oilin g a skate-roller without taking oithe roller, and to provide an cfdeient retraotingspring a-dapted to the peculiar service required therefrom in this construction.

The improvements herein described and. shown are in the nature of improvements upon my patent of December 21, 1880, to which reference may be had.

In the drawings forming part of this specification, Figure 1 is a side elevation of the forward or sole-plate portion of a roller-skate, showing a part of its frame and. my improved adjustable axlesupport, partly in section, and one of its sides removed. section through the line 00 06, Fig. 1. Fig. Sis a view in section of one end of a roller-skate axle and wheel, showing my impro.ved axleskein in section. Fig. 4 is an under-side plan view Of a roIler-skate axle and wheels, its bolthub, a part of the frame, and my improved retracting-spring and Fig. 5 is a view of said retracting-spring detached from the axle-bolt hub.

In the drawin gs, A is the frame of the skate. i is a longitudinal slot in frame A. 0 is a movable axle-support. e is a screw passing through the two sides of support 0 and through slot t'. 'It is the serrated lower edge of frame A. B is the foot-plate of the skate. CZ is an inclined axle-bolt. F is the axle. (lx is the axle-skein. 'U is a longitudinal cavity in the skein co. ID' is a hole bored from the outside of the skein t Fig. 2 is a vertical into the cavity Q2. 7b is the axle n retraeting spring. 8 is the axle-bolt hub on axle F.

To provide for moving the axlesupport -c under frame A, and for firmly securing it therennder, I make that portion of the under edge of said frame, where the Support 0 is to be Secured, straight, as shown, and out a longitudinal slot, 75, in said frame on a line with its edge, and said edge may be provided With a series of serrations, 12, to provide means for securing said support against any possibility of' slipping on the frame, although said support can be fastened very securely without them. When the edge of the frame is so serrated, the bottom of the groove between the two sides of the support 0 is likewise serrated to match the edge of the frame, and thus interlock when the support is fastened to the frame.

I construct the axle-support c separate from frame A, and attach to it the usual inclined axle-bolt, d. Said support c is made with a groove in its upper edge, adapted to receive between its two sides the lower edge of frame A, as shown, and is provided with a sorew, e, entering freely through one of its Sides and the slot 73 in frame A, and serewing into the opposite side, and when the support c is fastened to said frame A, as in Fig. 2, the edge of thelatter is so tightly clamped between the sides of the support as to prevent its moving under any ordinary strain.

In the drawings only that part of the frame under the sole-plate of the skate is shown as adapted to receive the movable axle-support 0,- but, if desired, the frame under the heel-plate may be made likewise to receive a like support for the rear axle, and thus either or both axles be Secured adj ustably under the frame A.

In Fig. 3 is shown my improved axle-skein ai. This skein is pinned into the end of axle F, as in my said patent, but the skein is pierced from its outer end to form the cavity IU, and a hole, Qi', is pierced in it from the outside thereof into the said cavity 0.7, said hole o' opening about opposite the center of the wheel-hub, as shown. The axle-skein, made as above deseribed, provides very convenient means for conveying oil directly to the inner surface of the wheel, which runs against the skein, by introducing oil into cavity 17, from whence it flows, through the hole o ,into the wheel-huh,

and properly lubrieates it without having to remove the wheel for that purpose, and when the wheel is secured to the axle by a solidheaded slrein, as here shown, this is particularly desirable, as oil can only with difficulty be introduced between the slrein-head and the wheel-hub, so as to have it properly reach the interior of the hub.

In my said patent the spring IL, whose use is there described, is sl1own as made from a single strip of metal. This is efficienton skates worn loy light siraters, but under other circumstances it is desirable to have a spring of much greater resistance, strength, and flexibility than can be made from a single strip, therefore I make the springt, heroin shown, Of two or 1nore leaves, l 2 3, and form it to partially enoircle the axle-bolt hill) 8, and have its ends bear against the sides of support 0, or of the frame A, as they do in my said patent, and for the purpose therein set forth.

It is obvious that other means than precisely those herein shown for fastening the support 0 to frame A may be used-as, for instance, a series of holes may be pierced throughsaid frame, through which screw 6 may pass, instead of through a slot, and the groove in the upper edge of said support may be clispensed With, and the support be bolted at different points along on the side of said frame, but neither of said modified modes of fastening would essentially change this feature of my invention, which consists, essentially, in so constrnetin g the forward axle support and frame of a roller-skate that said forward axle may be moved to and Secured at different points upon said frame under the sole-plate of the skate.

What I claim as ruy invention is- 1. In combination, the frame ofa roller-skate constructed without aforward axle-support, the movable a-xle-support c, having upon it the inclined axle-loolt d,and appliances, substantially as described, for securing said axle-support to said frame at different points under the soleplate of the skate, substantially as andfor the .purpose set forth.

2. The combination, with the azrle F and the wheel of a roller-skate, of the slrein ct, seeured to said axle, and having pierced therein the cavity 17 and the hole 'IJI, substantially as and for the purpose set forth. r

3. In combination with theaxle F, having thereon the axle-bolt hub 8, and with the frame of a roller-skate, the spring IL, consistin g of two or more leaves, 1 2 3, adapted to partially encircle said hub, and having arms overlappin g the frame, substantially as and for the purpose set forth.
